The Ronin 3.0 is a modular Geometry Hookah consisting of a metal flask with a main and a diffuser stem, and a walnut-wood sapboard; the flask can also be used on its own as a standalone hookah without the sapboard. The flask attaches to the sapboard with a magnetic connector, and in that configuration smoke additionally passes through a horizontal channel in the sapboard; a marking on the flask body indicates water level. There are three purge valves, 8 mm in diameter each, located at the top of the hookah; internal stem diameter is 11 mm, the molasses-catcher thread is M14 with a 1 mm pitch, and the hose connection is magnetic. Set weight is about 6 kg.
